This fit is calculated for the concerns frequently associated with oily skin: shine, enlarged pores, blackheads, and blemishes. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for oily skin; other serums fit it better.

## Why this fit

- Offers moderate retinoid benefits for your oily skin, with hydroxypinacolone retinoate and retinol promoting cell turnover to address fine lines and wrinkles.
- While it provides general hydration and soothing from ingredients like honey extract and bisabolol, it lacks sufficient seboregulating components to optimally manage oily shine.
- The formula is safe for your oily skin, as it contains no harsh ingredients and includes soothing agents like bisabolol and honey extract to minimize irritation risk.

## Questions and answers

### How well does Sunday Riley A+ High-Dose Retinoid Serum work for oily skin?

Sunday Riley A+ High-Dose Retinoid Serum works moderately well for oily skin by offering cell-renewing retinoids, though other products fit this skin type better. It lacks enough oil-controlling ingredients to properly manage shine, so an oily skin product needs ingredients like niacinamide and zinc PCA to control sebum and keep pores clear.
Sources: [Journal of Cosmetic Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/36762391/)

### Which ingredients make this serum a good fit for oily skin?

This serum fits oily skin by using hydroxypinacolone retinoate and retinol to speed up cell renewal, alongside honey extract and bisabolol to help keep the skin calm. However, an oily skin type needs ingredients like niacinamide, zinc PCA, or ferulic acid to properly control excess oil and shine.
Sources: [Journal of Cosmetic Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/36762391/)

### What does Retinoid do for oily skin?

Retinoid helps manage oily skin by reducing oil production and keeping pores clear. This type of ingredient works best when paired with oil-controlling and pore-clearing ingredients to keep skin balanced and smooth.
Sources: [Journal of Dermatological Science, 2013](https://pubmed.ncbi.nlm.nih.gov/23473858/), [The Journal of Investigative Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28259683/)

### What does Coenzyme Q10 do for oily skin?

Coenzyme Q10 helps energize cells and fights free radicals in stressed skin. It is unlikely to cause greasiness, but oily skin also needs lightweight hydrators and balancing ingredients to stay clear and smooth.
Sources: [BioFactors, 2015](https://pubmed.ncbi.nlm.nih.gov/26648450/)

### Where does this serum go in a skincare routine for oily skin?

This serum goes in the evening routine after cleansing and toning, and before moisturizing. It works for oily skin by offering moderate retinoid benefits, but an oily skin routine also needs oil-controlling ingredients to properly manage shine.

### Can I use this serum with vitamin C, and in what order?

You can use this serum with vitamin C by applying vitamin C in your morning routine and this treatment at night, as it lacks sufficient oil-controlling ingredients for oily skin.

### How often should I use this serum?

This serum works well in your evening routine, and you can start using it once a week to see how your skin responds. While it is safe and provides gentle hydration, this type of skin needs a product with ingredients that actively help control excess oil.
Sources: [Journal of Cosmetic Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/36762391/)

### Can this serum clog pores, cause breakouts or purging for oily skin?

This serum is unlikely to cause clogged pores or breakouts for your oily skin, though you may experience a low chance of initial purging as the retinoids speed up cell turnover. An oily skin type needs lightweight formulas with oil-controlling ingredients to properly manage shine.
Sources: [Journal of Cosmetic Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/36762391/)

### Is this serum fragrance-free and alcohol-free?

It has no fragrance and contains drying alcohol (alcohol).
